HIGH SPEED OVERLAY MODE FOR BURST DATA AND REAL TIME STREAMING (AUDIO) APPLICATIONS |
| 摘要 |
In a wireless 802.15.4 communication system (300), a high-speed data frame structure (340) is provided which uses the 802.15.4 SHR structure that is spread modulated to obtain the synchronization benefits of the 802.15.4 protocol, but which uses a modified data frame structure for the payload portion without using spreading to thereby improve its transmission efficiency. The transmission efficiency can be further increased by increasing the size of the data payload (and correspondingly, the frame length size). |

1. A data reception method for demodulating a data packet in a wireless receiving device, comprising:
demodulating a first part of the data packet by despreading only selected data bits in the data packet; and separately processing at least a data payload portion of the data packet so that the data payload portion is not despread. |
